CHARLES H. KOHLER, OF CLEVELAND, OHIO.

SPECIFICATION forming part of Letters Application filed November 14, 1879.

To all whom it may concern Be it known that I, CHARLES HENRY Kon- LER, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Improvement in Extinguishing Tubular Lamp-Burners; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing, and to the. letters of reference marked thereon.

My invention relates to certain improvements in kerosene or fluid lamps, and the object I have in view is to so construct and arrange burners for tubular or similarly-arranged wicks or wick-holders that the lamp can be readily and conveniently extinguished without turning or blowing out the flame.

I attain this object by the mechanism illustrated in the accompanying drawing, which is a sectional view of my improved burner, showing the arrangement of the various parts for accomplishing the purpose intended.

A represents a sleeve fitting over the upper part of the tubular wick-holder B, the conical shape of which is modified at the top, so as to form a cylindrical extension within the sleeve, for the purpose of preventingthe admission of air between the sleeve and tube, which would result if the conical shape were maintained when the sleeve is raised above said tube.

If B were made of conical shape for its entire length, the sleeve A, to fit thereon, as is necessary, also would have to be conical in shape. If this were the case, upon raising the sleeve there would be a space between the tube and sleeve, so that the air could not be shut off from the flame, and it would not be extinguished; hence the reason of my using the above-described sleeve and wick-holder.

0 represents an inner tube for conducting air to the flame. This tube moves freely within the wick-tube B, its lower end resting upon a support inside said tube, arranged as shown, while its upper end is flush with that of tube B and forms a continuation of the inner lining of said tube, which extends only to about the point where the modification heretofore described begins.

The air is admitted within this tube through an opening in the side of the wick-tube and corresponding openings through its side, as shown. The opening in the wick-tube is V- Patent No. 239,964, dated April 12, 1881. Patented in England March 21, 1877.

shaped, and extends from the base of the airchamber, where it is broadest, to a point a short distance below the sleeve fitting upon said tube. This opening is represented by b in the drawing.

The openings in tube 0, which are represented by the letters a c, are separated by the continuation of .the sides of said tube at the point 01. If this division were not made, the air-opening in tube 0 would conform in shape to that in tube B.

1) represents an arm, by means of which the sleeve A and tube 0 are firmly united, said arm being fastened to the lower part of said sleeve, and then, passing down outside of the wick-holder B, enters the air-opening b, where it is joined to tube G at the point 01, as shown.

By this arrangement the connected parts will move simultaneously, and upon being raised above the wick-holder will shut off the air from both sides of the wick at the same time and in the same operation.

Forthe purpose of raising and lowering these connected parts I employ alever, E, which has its inner end passed through a slot, 0, near the bottom of tube 0, while its outer end passes through the sides of the air-chamber, where it is properly fulcrumed to be readily operated by the hand.

From the above description it will readily be seen that by depressing the free end of lever E the inner tube 0 and sleeve A, connected therewith by arm D, can be raised together, and thus in a simple and efficient way instantly extinguish the flame.

The tube 0 andsleeve A are so arraugedin relation to each other by means of the arm D that when tube 0 rests upon its support the sleeve A has its upper end a little below that of the wick-tube B, as shown.

Arm D is limited in its vertical movement by the upper part of opening b, against which it will strike when the tube and sleeve have been raised the proper distance by the lever operating them.

The simplicity of construction in my device obviates any tendency to failure in case of emerfastened to the neck of the burner, as shown,

the flame of the lamp may be automatically extinguished in case itshould be overturned, as Very frequently happens, said weight falling from its cup and depressing the lever to which it is attached, and thus raising the sleeve and inner tube above the level of the Wick and instantly extinguishing the flame; but I do not claim this construction, as the principal features of my device are embraced in the simultaneous movement of the inner tube and sleeve and the cylindrical shape of the upper part of the wick-tube, whereby air is prevented from entering between the sleeve and said tube, as here tofore described.

23d day of June, 1879. C. H. KOHLER.
